Let a = 6, the initial number of books read \n" ); document.write( "Let b = 2, the amount that the value grows by (doubles)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "x represents the number of years since age 6\r \n" ); document.write( "\n" ); document.write( "At age 10, that is 10-6 years since age 6, or four years since age 6.
